Benefits of technology

[0008]Exemplary embodiments of the present invention provide display devices including lower barrier layers having single layer structures to prevent a decrease of transmittance and damage thereof.
[0031]According to exemplary embodiments of the present invention, the lower barrier layer having a single layer structure may be provided on the rear face of the first substrate so that damage, deterioration, and / or degeneration of the first substrate may be significantly reduced or substantially prevented. Accordingly, failure such as haze may not be generated in the first substrate to prevent the decrease of transmittance of the display device. Further, the lower barrier layer may effectively prevent moisture and / or oxygen from permeating the inside of the display device through the first substrate, such that the display device may have improved performance and durability.

Problems solved by technology

A flexible substrate in a conventional flexible display device may have relatively high water vapor permeability, so that moisture may permeate inside of the flexible display device and deteriorate or damage elements of the flexible display device.
Additionally, the flexible substrate may be damaged or the optical properties of the flexible substrate may be deteriorated, when the flexible substrate is separated from a support substrate when manufacturing the flexible display device.
Accordingly, failure such as haze may not be generated in the first substrate to prevent the decrease of transmittance of the display device.

Embodiment Construction

[0038]In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments. It is apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various exemplary embodiments.

[0039]In the accompanying figures, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity and descriptive purposes. Also, like reference numerals denote like elements.

[0040]When an element or layer is referred to as being “on,”“connected to,” or “coupled to” another element or layer, it may be directly on, connected to, or coupled to the other element or layer or intervening elements or layers may be present. When, however, an element or layer is re...
